President's Message

Our heartfelt thanks to Dr. Roy Chemaly, for his outstanding service as the ICHS President and for his dedication in spearheading the planning of the ICHS 24th Biennial Symposium over these past two years!
The symposium offered four days of comprehensive scientific programming, insights into cutting-edge research, innovative care practices, and effective management strategies for immunocompromised hosts with a diverse range of plenary and concurrent sessions, poster presentations, and clinical grand rounds discussions. Opportunities to engage with peers, exchange ideas, and foster collaborations were prevalent to help shape the future of our field of management.
